What Are the Symptoms of Thumb Tendinitis?

In our joints, tendons are distributed relatively densely. Once they are frequently overused, leading to excessive use of muscle fibers, lesions can occur, resulting in the emergence of tendonitis and even affecting the tendon sheath. The causes of articular tendonitis vary depending on the location of the disease, and the main clinical symptoms include joint stiffness, numbness, stabbing pain, mild swelling, and other discomfort symptoms. Tendons are strong fibrous connective tissues that connect bones and muscles. Tendonitis usually refers to degenerative changes in tendon collagen fibers caused by excessive use of muscle fibers and repeated strong traction. In addition to affecting the tendons themselves, it can also affect the tendon sheath. Tendonitis was previously commonly used in diagnosis, but in fact, it is not a single inflammation. In most cases, it is often accompanied by degenerative changes in the collagen tissue of the affected tendons, so it is now generally referred to as tendon disease. The most common chronic diseases related to exercise are Achilles tendon disease, patellar tendon disease, quadriceps and hamstring tendon disease, rotator cuff tendon disease, and lateral epicondylitis ("tennis elbow"). It is caused by excessive use of muscle fibers and repeated strong traction, which is the result of the interaction of endogenous and exogenous factors. Endogenous factors include body-related factors such as poor alignment and poor muscle strength. Exogenous factors include training errors, poor equipment and techniques, and changes in the venue. The interaction of external factors can also lead to the occurrence of tendon disease. External factors include training errors such as distance, intensity, slope exercise, technique and fatigue, training venue, etc. These factors play an important role in acute injuries. Tenderness around the joints or near the joints, especially around the shoulder, wrist, or Achilles tendonitis, or the lateral side of the elbow (tennis elbow), may occur with numbness or stabbing pain, accompanied by painful joint stiffness, limiting the movement of the affected joints. Occasionally, there may be mild joint swelling, persistent pain, and continued pain or recurrence of the tendon after the original injury. If the pain persists for 7 to 10 days without improvement, and the pain is severe with swelling, there may be tendon rupture, and immediate treatment is required. Avoid transforming into chronic tendinitis or combining with other diseases such as bursitis, carpal tunnel syndrome, or phlebitis. Pain, tenderness, dysfunction, and inflammatory reactions occur at the lesion site. The pain is aggravated during repeated traction activities and may also occur during rest. Inflammatory edema of the tendon or tendon sheath leads to pain and dysfunction at the lesion site. The clinical manifestations vary depending on the location of the lesion.
